Motorized Zoom Zoom Day and Night Camera Lens

Abstract

The invention relates to an electric-zooming day and night dual-purpose pick-up lens. The electric-zooming day and night dual-purpose pick-up lens is characterized in that an optical system of the lens is provided with a front group A with negative focal power and a rear group B with positive focal power in sequence along the light incident direction from left to right, and a variable diaphragm C is arranged between the front group A and the rear group B; the front group A comprises a negative crescent type lens A-1, a double-concave lens A-2 and a positive crescent type lens A-3 which are arranged in sequence; the rear group B comprises a convexo-plane lens B-1, a positive crescent type lens B-2, a double-convex lens B-3, a gluing group for close connection of a double-concave lens B-4 and a negative crescent type lens B-5 and a convexo-plane lens B-7. The electric-zooming day and night dual-purpose pick-up lens has the advantages that the image definition is improved, the image quality is improved, the cost is reduced, the focus can be automatically controlled, and the pick-up system can realize the requirement of the scene for high-definition picking up in the variation-range environment.

Description

technical field [0001] The invention relates to an electric zoom and zoom day and night camera lens, which belongs to the field of optical camera devices of video technology. Background technique [0002] As we all know, my country has a vast territory and spans multiple climatic zones, so it is bound to be restricted by many natural environments: fog, high temperature or low temperature, etc. In addition, although the functions of cameras are becoming more and more abundant, they still cannot achieve flexible monitoring in areas with frequent environmental changes. Setting; due to the production of electric zoom lenses, it is affected by design, product raw materials, key technologies and other aspects. Although Chinese companies have good designs, due to other conditions, they are able to produce and sell them. In fact, very few , and the effect is not good. The performance index is low, and the definition of the image only reaches 200,000 to 300,000. Contents of the inve...
